white fine powder

The Uses of Dibutyltin oxide

Dibutyltin oxide is used in studies pertaining to discovering novel antitumor agents. Antifungal activity.

The Uses of Dibutyltin oxide

Di-n-butyltin oxide is used as a reagent and a catalyst. It is particularly useful in regioselective alkylation, acylation and sulfonation reactions for starting materials containing alcohol functional groups. It is used in studies pertaining to discovering novel antitumor agents, antifungal activity.

Flammability and Explosibility

Non flammable

Safety Profile

Poison by ingestion and intraperitoneal routes. A skin and eye irritant. Flammable when exposed to flame; can react with oxidizing materials. To fight fire, use dry chemical, fog, CO2. When heated to decomposition it emits acrid smoke and irritating fumes. See also TIN COMPOUNDS.

Purification Methods

It is prepared by hydrolysis of di-n-butyltin dichloride with KOH. Hence wash it with a little aqueous M KOH, then H2O and dry at ~80o/10mm until the IR is free from OH bands. [Cummings Aust J Chem 18 98 1965, Beilstein 4 I 588.]
